Flat link versus a deliberate unfurl
Same article. Two outcomes.
| Element | Weak share | Strong share |

The second column is not luck. You set the Open Graph properties once per template or per page, then validators confirm what crawlers cache.
From your fields to the head tag
You type plain text and URLs. The script escapes them for HTML attribute safety, then prints a block you paste inside <head>.
Open Graph uses property attributes (for example og:title). Twitter Cards reuse your title, description, and image while adding twitter:card so X knows whether to expect a large image frame.
We also echo a standard meta name="description" and a canonical link so your HTML stays coherent for search bots and social bots in one pass.
When production still disagrees with this preview
Caches win arguments. Facebook, LinkedIn, and X each keep their own snapshot of your URL. After you ship new tags, run each platform debugger, fetch the URL again, and wait for the refresh to stick.
This generator does not ping those services. You still own the deploy step, the SSL certificate on your image host, and the choice to block bots with robots rules.
Who usually needs this workflow
Marketing folks validating a launch page before paid social goes live. Developers wiring a static site or SPA who want a reference snippet without digging through vendor PDFs. Freelancers sending clients a visible mock before handoff.
